This document provides information on:
•important pre-installation considerations
•power supply requirements
•initial handling procedures
•installing the module
•using the indicators on the module for troubleshooting
•module specifications
This module must be used in a 1771-A1B through -A4B or later I/O
chassis.This module does not contain surge limiting circuitry. Use
this module for switching resistive loads only. It is not
recommended for inductive or capacitive loads.
The outputs are arranged in 4 groups of 8, each group with its own
common. The module can simultaneously switch all 32 outputs to
separate loads, with a maximum of 12A per module. Each output
can conduct a maximum load of 1.0A continuously at 30W
maximum. Ac loads switched by the modules should have a power
factor (PF) of 1.0.
Maximum interconnect cable length for this module is 1000 ft.
(304.8 meters).

Low Voltage Directive
This apparatus is also designed to meet Council Directive 73/23/EEC
Low Voltage, by applying the safety requirements of EN 61131–2
Programmable Controllers, Part 2 – Equipment Requirements and
Tests.
For specific information that the above norm requires, see the
appropriate sections in this manual, as well as the following
Allen-Bradley publications:
•Industrial Automation Wiring and Grounding Guidelines,
publication 1770-4.1
•Guidelines for Handling Lithium Batteries, publication AG-5.4
•Automation Systems Catalog, publication B111
The controller or I/O chassis power supply, connected through the
backplane of the I/O chassis, powers the logic circuitry of the contact
output modules. This supply also provides the necessary power to
energize the coils of the module relays. The maximum current drawn
from this supply when all coils are energized is 2.5A. Nominal
backplane current is 1.8A.
When handling the module, observe the following warning:
!ATTENTION: Remove power from the 1771 I/O
chassis backplane and field wiring arm before
removing or installing an I/O module.
•Failure to remove power from the backplane or wir-
ing arm could cause module damage, degradation of
performance, or injury.
•Failure to remove power from the backplane could
cause injury or equipment damage due to possible
unexpected operation.
The contact output module contains components which can be
damaged by electrostatic discharge. The module is shipped in an
electrostatic shielded bag for protection. Follow the handling
procedures outlined below to guard against damage to your module.
•Touch a grounded object to discharge yourself before handling
the module.
•Do not touch the backplane connector or connector pins.
•If you configure or replace internal components, do not touch
other circuit components inside the module. If available, use a
static-safe work station.
•When not in use, keep the module in its static-free shield bag.

3 Selectable Contact Output Module Cat. No. 1771-OWN
Publication 17715.37 - October 1995
In this section we tell you how to key your I/O chassis, set the relay
output jumpers, install your module and make your wiring
connections.
Keying the I/O Chassis
Use the plastic keying bands, shipped with each I/O chassis, to key
your I/O slots to accept only this type of module. Place the keying
bands on the chassis backplane between:
•6 and 8
•16 and 18
Slots on the rear edge of the circuit board are matched to these slots
to allow insertion of this type of module. You can key any connector
in an I/O chassis to receive this module except for the leftmost
connector reserved for adapter or processor modules.
Setting the Relay Output Jumpers
When the output image table bit at the address corresponding to any
output is energized (set to 1), the corresponding relay contact is
closed or opened, respective to the jumper setting.
All outputs are individually selectable for either normally-open or
normally-closed operation. They are pre-set for normally-open
operation at the factory. To reset any jumper, proceed as follows:
1. Remove the 4 screws from the side cover and separate the circuit
board from the 2 covers.
2. Move the jumper to the desired position. Jumpers are identified
by jumper number and use (N.O. or N.C.). Refer to Table 1.A for
jumper and terminal identifications.
3. Reinstall the circuit board in the module and replace the cover.

Inserting the Module Into the Chassis
1. Turn off power to the I/O chassis.
2. Position the module so that the circuit board on the rear of the
module lines up with the top and bottom card guides in the
chassis.
3. Slide the module into the chassis.
4. Press firmly to seat the module in the chassis backplane
connector.
5. Swing the module locking latch down into place over the front
edge of the module.

Connecting Wiring to the Module
You make connections to the module through the field wiring arm
cat. no. 1771-WN. The arm pivots on the I/O chassis to connect with
terminals on the front of the module and acts as a terminal strip. The
wiring arm allows the module to be removed from the chassis
without disconnecting wiring.
1. Make certain all power is removed from the module before
making wiring connections.
2. Swing the wiring arm up into position on the front of the module.
The locking tab on the module will secure it into place.
3. Make your connections to the field wiring arm as shown in the
connection diagram. (Use the label on the front of the wiring arm
to identify your wiring.)
!ATTENTION: The field wiring arm terminal
identification number is not the same as the number of
the bit which controls that output.

!ATTENTION: Do not attempt to increase load
current or wattage capability beyond the rating by
connecting two or more outputs in parallel. The
slightest variation in output relay switching time may
cause one set of contacts to switch the total load
current.
You can use the 1771-OWN output module to drive an input of a
120V ac input module (1771-IA, -IA2, -IAD) to indicate status of
turning on a motor starter as shown below, for example, but you
must connect a 15K, 2W resistor between the output and L2
(common). Inputs configured with the output module are not isolated
from each other.
